Commands
Resize Images
python scripts/main.py resize ./images/ --width 1200
python scripts/main.py resize ./images/ --format instagram # 1080x1080
python scripts/main.py resize ./images/ --format linkedin # 1200x627
Compress Images
python scripts/main.py compress ./images/ --quality 80
python scripts/main.py compress ./images/ --max-size 500 # Max 500KB
Remove Background
python scripts/main.py remove-bg photo.jpg
python scripts/main.py remove-bg ./products/ --output ./transparent/
Add Watermark
python scripts/main.py watermark ./images/ --logo logo.png --position bottom-right
python scripts/main.py watermark ./images/ --text "© 2024 Company" --opacity 0.3
Convert Format
python scripts/main.py convert ./images/ --format webp
python scripts/main.py convert ./images/ --format avif --quality 80
Examples
Example 1: Prepare Product Images for E-commerce
# Remove backgrounds
python scripts/main.py remove-bg ./raw-products/ --output ./transparent/
# Resize to standard size
python scripts/main.py resize ./transparent/ --width 1000 --height 1000 --fit contain
# Compress for web
python scripts/main.py compress ./transparent/ --quality 85 --format webp
# Output: ./transparent/*.webp (optimized, transparent background)
Example 2: Social Media Image Kit
# Create multiple sizes from one source
python scripts/main.py resize hero-image.jpg --format instagram --output hero_ig.jpg
python scripts/main.py resize hero-image.jpg --format linkedin --output hero_li.jpg
python scripts/main.py resize hero-image.jpg --format twitter --output hero_tw.jpg
python scripts/main.py resize hero-image.jpg --format facebook --output hero_fb.jpg
# Or batch process entire folder for one platform
python scripts/main.py resize ./campaign-images/ --format instagram --output ./instagram/
Example 3: Website Image Optimization
# Convert all images to WebP
python scripts/main.py convert ./website-images/ --format webp --quality 80
# Ensure no image exceeds 200KB
python scripts/main.py compress ./website-images/ --max-size 200
# Results in 60-80% smaller file sizes
